Population Movement In 2000 the U.S. population, broken down by regions, was 53.6 million in the Northeast, 64.4 million in the Midwest, 100.2 million in the South, and 63.2 million in the West. $^{3}$ In 2010 the population was 55.3 million in the Northeast, 66.9 million in the Midwest, 114.6 million in the South, and 71.9 million in the West. Set up the population figures for each year as a row vector, and then show how to use matrix operations to find the net increase or decrease of population in each region from 2000 to 2010. Assuming the same population growth from 2010 to 2020 as from 2000 to 2010 , use matrix operations to predict the population in each region in 2020 .
